DANIEL KELLY AND WM. LIVINGSTON, OF GRAND RAPIDS, MICHIGAN.

WINDOW-BLIND.

Specification of Letters Patent No. 16,632, dated February 10, 1857.

To all whom it may concern:

Be it known that we, DANIEL KELLY and IVILLIAM LIVINGSTON, of Grand Rapids, in the county of Kent and State of Michigan, have invented a new and useful Improvement in the Construction of IVindowBlinds; and we do hereby declare thatthe following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making` a part of this specification, in which- Figure l is a transverse vertical section of our improvement. Fig. 2 is a detached face view of one of the slats. Fig. 3 is a horizontal section of the same; in Fig. 1 showing the plane of section.

Similar letters of reference indicate corresponding parts in the several iigures.

This improvement in the construction of blinds is for the purpose of rendering them weather-proof, and also enabling` them to exclude the lightI when the slats are closed.

The invention consist-s in having the slats of the blind so constructed or formed that the portions above their axes or pivots will be out of line with the portions below it, and thereby allow the slats, when closed, to t together in such a manner that one will be flush with the other; the portions of the slats below their axes or pivots being a trifle longer than the upper portions, so that. weather strips may be secured to the st-iles of the blind and interposed between the end of the upper .portions of the slats and the stiles.

'Io enable those skilled in the art to fully understand and construct our invention, we will proceed to describe it.

The frame of the blind is constructed in the usual manner.

A, A, represent the two stiles; see Fig. 3; B, Fig. 1, is the top rail, and C is the bottom rail.

D represents the slats, constructed ofwood, and each having a tenon (a) formed at the center, of each end to serve as pivots or axes for them to' turn or work upon. The tenons (a) are fitted in holes made in the sides of the stiles, A A, as usual.

The upper portions (b) of the slats, the portion above the line of their tenons or axes (a) are not in line or in the same plane with the lower portions (c) as shown clearly in Fig. l; the upper and lower portions of the slats being cut out or reduced in thickness about one-half at opposite sides. The slats are so placed in the frame that, when closed, they will overlap each other, about one-half their width; the upper portion (b) of one slat fitting snuglyagainst the lower portions of the one immediately above it, as shown clearly in Fig. l.

The top rail B has a pendent plate or lip (d) attached to its under surface, against which the upper portion of the top slat bears, that is, when the slats are closed. The upper port-ions (7)) of the slats are rather shorter than the lower portions (c) as shown clearly in Fig. 2; and a strip (c) is secured to the inner side or edge of each stile A, as shown clearly in Fig. 3; the upper portions (o) of the slats being fitted and working between the strips (c) and the lower portions (c) between the stiles. The slats are connected to a rod E by staples (f) in the usual way.

In consequence of the slats being constructed as shown, they will when closed form an even or smooth surface at each side, one slat being Hush with the other; and as the ends of the lower portions (c) of the slats bear against the strips (c), and the upper portion (.72) of one slat bears against the lower portion (c) of the one directly above it, a weather-tight joint is formed at the ends of the slats, and also a perfectly weather-tight lap. The light is also perfectly excluded when the slats are closed.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is:

Constructing the slats, D, as shown, and having strips (c) attached to the stiles, as described, whereby the slats, when closed, will overlap and be flush with each other, at each side, and the slats rendered perfectly weatherproof, and the light excluded.
